To all wlzom "it may concern.-

Be it known that we, .l-Inxnr B. Benson and AN- DREW HAUG, citizens of the United States, residing at N ew-York, county and State of New York, have invented certain new and useful Improvements in Tall;- ing-Machines, of which the following is a specification.

Our invention relates generally to talking machines and particularly to supporting means for the sound reproducer thereof.

An important feature of our invention consists in mounting the sound reproducer insuspended relation on ball or roller bearings so arranged, as to permit free movement thereof only in planes at right angles to each other.

In the present embodiment of the invention, the reproducer is preferably mounted upon ball-bearings and is free to move vertically and horizontally in accordance with the requirements of the type of machine to which it is applied.

The accompanying drawings will serve to illustrate mechanism suitable for carrying (iur invention into effect. We wish it understood, however,- that we do not limit ourselves to the exact construction and arrangement of parts shown, as various changes maybe made therein or other means employed operating in substantially the same manner to the same result.

In the drawings: Figure l, is a view inside elevation, partly in section, illustrating the application of our invention to a' well-known type of talking. machine.

Fig. '2, is a horizontal sectional view thereof, on the line s, 5 of Fi 1, and Fig. 3, isa detail view of the stamped out blank which is shown in Fig. 2, formed up to serve as a removable ring section of the horn supporting bracket.

Referring now to the drawings: 1, represents the easing of the machine, 2, the rotating table thereof, 3, the

usual type of disk record upon the table, 4, the sound box or reproducer, 5, a rigid arm or bracket secured to 40 the casing by screwsB, or otherwise, and '7, the horn,

the small end 8 of which, is removably fitted in a sleevelike oft-set or annular guide 9 of the bracket 5, the arrangeinent being such as to permit the horn to be swung around to any position desired.

Interposed between and operatively connecting the reproducer or sound bolt and the horn, there is a tubular sound conveyer' 10, known generally as a taper arm.

The reproducer is secured to one end of the arm, which forms a continuation of the sound chamber thereof. The arm 10, may be cast, drawn, stamped up from sheet metal or otherwise formed and terminates at the end I opposite the reproducer in an elbow 1.1, which is provided with a shaped portion 12 fitted in the bore of the sleeve or annular guide 9 oi the horn supporting bracket. As arranged, the co-acting bearing surfaces of the arm and guide are tangentially disposed relatively to each other, permitting irce vertical and horizontal movement of the arm with a minimum amount of friction. The arm'is supported in suspended relation in the guide upon ball bearings 13, which are diametrically disposed and cooperate with the guide to limit the arm' to movement in planes at right angles to each other or as shown, to vertical and horizontal movement only, thus maintaining the reproducer in proper position relatively to the record. The arm is provided with semi-spherical indentations, or other suitably formed recesses, slots, or the like, as indicated at 14, to receive the balls, which project outwardly therefrom in opposite directions and enter slots or recesses 15 of the guide. The length of the arc through which the arm is movable horizontally determined by the length of the slots 15 and r therefore, be varied as required.

Fprconvenience in assembling the parts, the annular guide for the arm is preferably formed as a remov able ring section 16 of the bracket 5, which latter is counterbored to receive the same. This ring section may be blanked out, as shown in Fig. 3 and subsequently formed up, -or it be cast or otherwise pro- I or other suitable means. i

A spring locking device 18, such that shown or of any other suitable form, may be employed to yield. ingly hold the reproducer elevated above and clear of the record when the machine is not in use.

The operation, advantages, etc., of our invention wiil be apparent fromthe foregoing description.

Having thus described our invention, we claim:

1. A support for a sound reproducer comprising an annular slotted guide, a tubular arm forming acontinuation of the reproducer and terminating within the guide, and balis in the slots serving'ns'bearings upon which the arm is free to swing vertically and horizontally.

2. A support for a sound reproducer comprising an arm forming a continuation of the reproducer, and hearings on ASSIGNORS 'ro UNIVERSAL ornnn MANUFACTURING OOMPAN A CORPORATION on new YORK.

which the arm is free to swing vertically and horizontally, said bearings being movable with the arm and free to 1'0- tate indvpendvntly thereof.

34 A support for a sound reproducer comprising an arm forming a continuation of the reproducer. hearings on which the arm is free to swing verticallyand horizontally,
